Original application led July 18. 1907.. Serial Nm-384.732- Divided and this application filed T o all whom it may concern: Be it known that I, 'GILBERT W. Goon- RIDGE, a citizen .of the IUnited States of l America, .residing at Bridgeport, in the .'inall'y the socket shell is connected up to the cap. In mounting these sockets, particularly key sockets, on iiXturesand-,elsewheie, with ornamental husks, the 4key has to be arranged to project through one part of the ornamentalhusk and consequently the shell has to be put on in a certain position, considere'd rotarily. With the 'construction' of bayonet joints or othershell and cap fasten'- ings now in use, those two parts, the cap and shell, can. be fitted together only when brought into one certain' relation to each other, and since that. relationis apt to be such as not to permit the key to then pass into .thekel slot and through` the necessary slot in the "usk, the only remedy is for the. wireman' to unscre'w the' socket cap again and iile down its nipple sufficiently 'to per-- 'mit the cap when -screwed on the pipe end again to -be turned to a position where the socket key stem will suitably enterthe key vslot in the shell and also the slot-in the husk.

To meet this trouble I have .devised a new socket and shell fastening, which permits the shell to be appliedand; attached tothe cap in any relative rotary position 'ofthe twoy parts. This I accomplishby providing co- 'o eratin latching means on the two parts,

t e lato gelements on lone of the parts being greater .in number than on the other part and' many times re eated' and arrangedsymmetrically around t e circumference.

which are many timesl repeated and are symmetrically arrangedv around its circumference. The cooperating latching means on the shell A are shown as consisting of two angled tonguesc cut out of the metal of the shell and pressed outwardly, one cut or an le of each tongue being arallel with the' @n of the shell so that 'w en latched into 60 any opening dit will hold the shell and cap together'ag'ainst endwise motion. The otherangle 'of each tongue is substantially parallel with the axis of the shell' and the two angled vtongues being cut to face in the same direction as shown,t hey so engage the vside walls of the o enings d when latched asto prevent the shel from turning in the cap. To de- -tach the shell, pressure is applied bythe thumb on the'wall of theshe latch cadjacent to the key slot k.

It will thus be seen that owing to the num berof symmetrically arranged openings d in the cap the shell may be iitted and latched to the cap with a simple endwise movement 75 and with the key slot cin almost any position A(relatively to the ca p rotarily) which the conditionsmay require.

I do not wish to restrict myself to the preciseconstruction of latching means shown, 8o which ma be variedl in many ways-without escaping t e breadth of my inventioin I claim as my invention:

socket consisting of a 'shell and cap; of a 85l pluralit 'ofvengagmg means von each of said parts, t e engaging means'on one part being symmetrically repeated -around its circumference and exceeding in number-the means onthe otherpart. f

2. An electric lamp socket having the end 'of the Vshell provided with projections and" having the cap iiange provided with a', greater number of symmetrically arranged o enin s `with any of which the projections in t e she 9.6",

can latch.
